Subject: proxy server GET examples

Below are a number of requests showing what a WWW client sends to a proxy
gateway server, and what the server returns. There are examples for Gopher,
FTP, and HTTP. Notice that in all cases, the client actually speaks HTTP
with the proxy gateway server and uses the full URL in its GET method
request. The example proxy server is the cern_httpd 2.15 daemon. The client
is Lynx 2-2 with the modification that I used an Accept: */* rather than
the list of Accepts that Lynx normally sends. The client request is
separated from the server reply by a blank line. I've used "...data..." to
substitute for actual content returned by the proxy gateway server. I hope
this clarifies some of the confusion over what the client/server
conversation looks like.
